Purpose

This document provides a process for the refurbishment of Switches and Crossings (S&C) assets. 

The aims of this process are to:

a) improve scoping and planning of S&C refurbishment works to address S&C system risk;

b) promote optimal decision making to facilitate cost efficiencies and value for money;

c) provide additional guidance for the delivery of safe scoping and S&C refurbishment works, considering reasonable opportunity to replace legacy components with modern equivalents;

d) provide assurance that the S&C refurbishment works have addressed the track asset risk identified in the problem statement and the target asset life extension can be met; and

e) to provide alignment with Cost and Volume reporting structures.
